B'rooder, of which the following is a specification.

' air may be'regulated and the My invention relates to the class of devices above named and an object or" the invention, among others, is to provide a device of this class in the use of which the purity of the air and heat so tempered as to produce extremely efficient results.

'One form of device embodying the nvention and in the construction and use of enough for this purpose.

13 secured to the bottom of having inlet openings 14 through the botwhich'the object above set out, as well as others, may be attained is illustrated inthc accompanying drawings, in which- Figure 1 is a view tion through an incubator embodying my in.- vention. Fig. 2 is a view in horizontal section on plane denoted by dotted line 2-2 of Fig. 1.

While the case embodying the incubator may be of any desired form and construction I prefer to make it with an outer wall 5 and an inner wall 6, providing an air space 7 A. series of slats 8 form-the bottom of the egg chamber and an egg tray 9 islocated on these slats, this tray being of the usual form and construction consisting of slats upon which'the eggs may rest and between some of which the chickens may drop into the compartment 10 at the bottom oi. the case,

the openings'bet-ween the slats 8 being large Any means of supporting the case may be employed, legs 11 being illustrated herein for that purpose.

Mixers 1.2 are secured underneath the bottom of the case, any suitable number of which may be employed, two being shown herein. These mixers each consist of a cup the case and tom of the cup. A disk 1.5 is rotatably secured to the bottom of each cup outside thereof, these disks having openings 16 arranged to register with the openings 14: when the disk is in one position so that air may pass into the cup through a shield 17. This shield will be composed of any suitable porous material which will prevent fresh air from passingin too great a quantity into the chamber 10. By rotating the disks 15 in central vertical secsurrounding the upper ter so that no fresh air may pass into the cups, or the amountwhich will pass into the cups may be regulated. An inlet pipe 18 supplies air to each of the mixers from a supply pipe 19 so connected to the inlet pipes that the supply and flow will be uniform to all of the mixers.

A distributing box 20 is located in the upper part of the egg chamber, this distributing box having openings 21 and an outlet pipe 22 extending through the top of the case, An evaporating cup 23 is secured to the top of the outlet pipe, this evaporating.

a chamber cup having double walls formin 2% with outlet openings 25 there mm, which may be formed through the wall of the cup into the chamber 24.- and these openings are controlled as by a ring 27 having penings to register with th openin s 25 in one posithe openings therthrough and through the bottom of the cups are moved out of registion of the ring, but closing said openings when the ring is rotated to another osition. A heater 28 is located at one Sid of the case and is supported thereby in any suitable manner. This heater consists of a boiler having a water chamber 29 with fiues 30 extending upward -through the Water chamber from a heating chamber 31 and into an outlet chamber 32. The heater may include a lamp 33 suspended as by a bracket 34; from the case and having a chimney 35 projecting into a main line 36. A hot air chamber 37 is formed in the base of the heater, the supply pipe 19 hereinbefore de scribed conducting air from this hot air chamber. A hollow cap 38 is located on top of the boiler, this cap having a flange '39 part of the boiler and the space within this flange being of" dome shape to constitute the outlet chem ber 32 from which an outlet flue 40 extends to the atmosphere. The chamber within the hollow cap constitutes a distributing hot air chamber 41 from which a distributing pipe 42" conveys hot air to the distributing box 20. Circulating pipes extend from the boiler within the case, these consisting: of a lead 43 extending from the boiler. into the case and having two branches constituting an outer coil 44 and an inner coil 45 each coniiected with the return 46 to the boiler, which return drops, outside of the case, before it enters into the boiler, as shown in Fig. 2 of the drawings. A second evaporat- .ing cup 47 is located over the line 40, being suitable moist material. Both of the cups 13 y suitable means for venting the boiler 15 boiler, this having a removable cap 51 in be controlled. A faucet 54 may be used to a; overlying the outlet flue 40 controls the v so an actuatin rod 60 is connected with the der the influence of the atmosphere, will sisting of a band 63 surrounds the chamber admit air, or may be moved out of register 1 the distributing hot air chamber 41.

0 the latter, means for supplying air to said heating device, and a coil extending from said boiler to the interior of the case.

'2. In an incubator, a case, a, heating device, a hot air chamber surroundin said heating device and completely shut ofi therefrom, means for supplying air to said chamber, means for conducting said air to the interior of the case at the bottom thereof,

a second heating chamber removably located above the first and having a flue to conduct the heat from said heating device, means for supplying air to said second heat ing chamber independently of the heating device or first heating chamber, and means supported as by a bracket 48. The waste heat passing from the heater is thus utilized on evaporation purposes, the cup being filled with moist sand, water, or any other 23 and 47 are thus, by the use of waste heat, 0 erated to provide the room within which tlib incubator is located with the proper degree of moisture.

when it is being filled may be employed, as herein shown a vent screw 49 extending into the top of the boiler, as shown in Fig. 1.

,A filling tube 50 is used for filling the which a pressure valve 52 is located, this valve being located on a valve rod 53 loosely mounted in thecap, and by means of which the pressure, if any, within the boiler may the case at. the upper part thereof.
